The primary objective of this study is to prospectively assess in randomized fashion whether short term anti-seizure prophylaxis in traumatic brain injured patients decreases the incidence of seizures in the early post-injury period. A secondary objective is to evaluate whether there are differences in mortality, hospital length of stay, functional outcome at hospital discharge, hospital cost, discharge status (home, rehabilitation facility, etc.) for patients who receive and do not receive anti-seizure prophylaxis.

The efficacy of anti-seizure prophylaxis in head injury patients remains controversial. Current recommendations for the use of anti-seizure prophylaxis are based upon a single institution study that has not been reproduced with other studies contradicting their conclusions. The proposed study will be a randomized prospective study at Loyola University Medical Center to assess the efficacy of anti-seizure prophylaxis in patients who have suffered traumatic brain injury (TBI). Patients with suspected TBI will undergo computed tomographic (CT) scan of the head. Following identification of TBI on CT scan, patients will be randomized to one of two study groups. Patients will be randomized to receive a seven-day course of anti-seizure prophylaxis with levetiracetam (UCB Pharma Inc.; Keppra) or randomized to a study group that will not receive anti-seizure prophylaxis. Patients will be consented prior to entry in the study. Patients will be followed for a total of seven days post injury for clinical signs of seizure activity. Additionally, patients will be assessed at one month post injury for clinical signs of seizure activity.
